🍵 There have been discussions about monero-pow randomX improvements for newer processor versions. One idea came to my mind: How about doing a check if a tee (trusted execution environment) is available?

Those could provide shortcuts to make CPU's more efficient compared to that CPU's that are currently used by ASIC-producers?
